Description

PID (software) efficiencies...

  • For a check, have to first create a clean sample of the particle of interest
    • e.g. kaons for the aerogel cut efficiency
    • To create clean sample for checking aerogel, cannot use aerogel itself. Must use Cherenkov or something else.
  • For the study, make cuts to create the clean sample very tight (much stricter than normal)
    • Then take the ratio of events with the aerogel cuts required in the analysis
      • e.g. NPE>1 and without
    • The results are the PID efficiency
  • It is good to check the efficiency stability over all runs
